Thanks. What should be height of glass cabinets? Pls also answer my first question

A soft, warm grey shade would look lovely, and can be as dark or light as you want. A warmer shade will work with the brown stained wood floor, and the grey will complement the black granite. You could have an undertone of green, blue or tan if you didn't want a pure grey. And it would look nice with any silver metal hardware, either polished or satin/brushed, so you could choose pewter, chrome or nickel. It would still work with white trim too.

I looked at the brochure but I could not find exactly what color or pattern Caesarstone has in India. I'd like the look of a "marble" Caesarstone for the counters and the back splash with your blue cabinets. I don't know if this is possible, though. I have granite in my kitchen and I the have counter and back splash in the same granite and I have loved it for 15 years. Do they have induction cook tops in India? They are wonderful, too.

Your choices don't flow well to me. The flooring in your photo is pretty (very dark...are you okay with it showing every footprint, smudge, and dust bunny? If so, that's fine). From all of your options there I would do white cabinets with the Himalaya White granite. But you said ignore the granite. :) I would go for the gray cabinets with white quartz everywhere in that case, but personally I'd worry about gray cabinets being very dated in a few years. Is there another quartz option that you could pair with the white cabinets that is light in color and maybe has some movement, like LG Bianco Drift?
